The cooling passage of the target backboard 2 that the embodiment of the present invention provides was hollow structure originally, on this basis, increase in the cooling passage of target backboard 2 and magnetic conduction sheet 4 is set, and magnetic conduction sheet 4 is arranged at the magnetic field intensity Qiang district in magnetic field produced by multiple magnet 3, be equivalent to increase the thickness of the magnetic conduction entity in magnetic field intensity Qiang district target backboard 2, and magnetic conduction sheet 4 can absorb magnetic field energy and reduce magnetic field intensity, therefore, the magnetic field intensity through magnetic field intensity Qiang district can be reduced by adding magnetic conduction sheet 4, the magnetic field intensity difference between zones of different is made after target backboard 2 to reduce and reach unanimity, thus make the etch rate to target 1 zones of different approximately the same when magnetron sputtering, then the service life of whole target 1 can be extended, improve the utilization rate of target 1;Simultaneously as during magnetron sputtering, the etch rate of target 1 zones of different is essentially identical, form the film forming thickness on substrate to be coated accordingly also just uniformly, improve formation in the uniformity with the film forming thickness on film plating substrate.
In the present embodiment, produced by multiple magnets 3, the magnetic field intensity Qiang district in magnetic field is positioned at the end of target backboard 2, and magnetic conduction sheet 4 is arranged in the cooling passage of the end of target backboard 2;This is owing to the magnetic field distribution of magnet 3 is relevant with the magnet 3 installation arrangement mode at target backboard 2 back side.Magnet 3 in the present embodiment selects magnet arrangement mode as shown in Figure 4: concrete, target backboard 2 is preferably strip backboard, a part of magnet 3 is spaced at least three row along the length direction of strip backboard, remaining another part magnet 3 is arranged in two row along the width of strip backboard, and two row magnets lay respectively at the relative two ends of strip backboard;The magnetic field intensity Qiang district in magnetic field produced by multiple magnets is positioned at the two ends of strip backboard, is respectively provided with a magnetic conduction sheet in the cooling passage at the two ends of strip backboard.When multiple magnets 3 select above-mentioned arrangement mode, owing to magnet 3 substantially gathers at the two ends of target backboard 2, by stronger for the magnetic field intensity that causes target backboard 2 two ends, as shown in Figure 5, the density of line of magnetic force in the produced magnetic field of magnet 3 is gradually reduced from the two ends, left and right of target 1 to the middle part of target 1, namely magnetic field intensity produced by magnet 3 is gradually reduced from the two ends of target 1 to the middle part of target 1, therefore, a magnetic conduction sheet 4 it is respectively provided with in target backboard 2 two ends, for reducing the magnetic field intensity at target backboard 2 two ends, so as to reach unanimity with the magnetic field intensity in the middle part of target backboard 2, thus making when magnetron sputtering the etch rate of target 1 is reached unanimity.It should be noted that, the shape of target backboard 2 specifically can be determined according to the true form of target 1 and substrate to be coated, accordingly, the arrangement mode of multiple magnets 3 there is also multiple change, the magnetic field distribution that magnet 3 produces also can respective change, but magnetic conduction sheet 4 should be always positioned at Qiang district, magnetic field, its concrete riding position is looked concrete condition and is determined.
In the above-described embodiments, due to the middle part from the two ends of strip backboard to strip backboard, produced by multiple magnets, the magnetic field intensity in magnetic field is gradually reduced;Preferably, as shown in Figure 6, magnetic conduction sheet 4 is wedge shape magnetic conduction sheet, and the thickness of wedge shape magnetic conduction sheet is gradually reduced from one end of strip backboard to the middle part of strip backboard, for coordinating magnetic field intensity produced by magnet 3 by by force to weak change, strengthen the regulating effect to magnetic field intensity produced by magnet 3, make magnetic field distribution produced by magnet 3 tend to uniform.
In the present embodiment, the magnetic conduction sheet 4 particular location in target backboard 2 as in figure 2 it is shown, the bottom surface of wedge shape magnetic conduction sheet is parallel with the back side of target backboard 2, the inclined bottom surface of the inclined-plane opposite wedge magnetic conduction sheet of wedge shape magnetic conduction sheet.The bottom surface of wedge shape magnetic conduction sheet is parallel with the back side of target backboard 2, and placement is installed at the back side pressing close to target backboard 2, it is simple to ensure that wedge shape magnetic conduction sheet is connected with the firm of target backboard 2;The magnetic field intensity rate of change along strip carapace length direction is depended at the angle of inclination of wedge shape magnetic conduction sheet, if magnetic field intensity is high along the rate of change in strip carapace length direction, then the angle of inclination of wedge shape magnetic conduction sheet is big, if magnetic field intensity is low along the rate of change in strip carapace length direction, then the angle of inclination of wedge shape magnetic conduction sheet is little.
In the above-described embodiments, if the arrangement mode of the magnet 3 at target backboard 2 back side changes, then the corresponding magnetic field distribution produced of magnet 3 also can change, now the shape correspondence of magnetic conduction sheet 4 also needs to make change, the visual concrete condition of shape of magnetic conduction sheet 4 is triangular prism shaped, cylindrical etc., with the magnetic field intensity that can reduce magnetic field intensity Qiang district or increase the magnetic field intensity in magnetic field intensity Ruo district for condition.
In order to make the magnetic field distribution that the magnet 3 at target backboard 2 back side produces more uniform, in the present embodiment, as shown in Figure 6, being provided with at least three strip bulge 5 on the inclined-plane of wedge shape magnetic conduction sheet, each strip bulge 5 is just right with a line magnet.Owing to magnetic field intensity is relevant to the distance at a distance of magnet, namely more near at a distance of the distance of magnet, then magnetic field intensity is more big, therefore just region being thickeied further of the magnet 3 that target backboard 2 is arranged with row by wedge shape magnetic conduction sheet by strip bulge 5, just the magnetic field intensity in region being reduced further of the target backboard 2 magnet 3 with row arrangement can be made, namely reduce the magnetic field intensity of most high-intensity magnetic field further, make the magnetic field intensity of the zones of different after target backboard 2 more tend to uniform.
